设G(V,E)是阶数至少为2的简单连通图,k是正整数,V∪E到{1,2,3,…,k}的映射f满足:对任意uv,uw∈E(G),u≠w,有f(uv)≠f(uw);对任意uv∈E(G),有f(u)≠f(v),f(u)≠f(uv),f(v)≠f(uv);那么称f为G的k-正常全染色,若,还满足对任意uv∈E(G),有G(u)≠G(v),其中G(u)={f(u))∪{f(uv)|uv∈E(G),v∈V(G)}那么称,为G的k-邻点可区别的全染色(简记为k-AVDTC),称min{k|G有k-邻点可区别的全染色}为G的邻点可区别的全色数,记作xat(G).本文得到了联图Fn∨Pm的全色数.
Let G(V, E) be a connect graph with order at least 2, k an positive integer and f a mapping from V(G) ∪ E(G) to {1, 2,…, k}. For all u ∈ V(G), the set {f(u)} ∪ {f(uv) | UV ∈ E(G)} is denoted by C(u). If 1) for any uv, vw ∈ E(G), u ≠ w, we have f(uv) ≠ f(vw); 2) for any uv ∈ E(G), u ≠ v, we have f(u) ≠ f(v), f(u) ≠ f(uv), f(v) ≠ f(uv), then f is called a k-proper-total-coloring. If f is a k-proper-total-coloring, and 3) for any edge uv ∈ E(G), we have C(u) ≠ C(v), then f is called a k-adjacent vertex-distinguishing total coloring of graph G(k-AVDTC of G in brief) and the number Xat(G) = min{k | G has a k-AVDTC} is called the adjacent vertex-distinguishing total chromatic number of G. In this paper, we got the adjacent vertex-distinguishing total chromatic number of join graph Fn∨Pm.
